Closing windows CMD window after executing system and run through a certain algorithm

I want to use 'system' to open another software in cmd as well as forming a java socket between them to allow exchanging datas for calculation, as shown in the code below

% command to execute in cmd to form socket
commandString = strcat('"', this.FreeFlyerPath, 'FreeFlyer.exe"', ...
' -r -mp "', this.MissionPlanPath, '\sample.MissionPlan"', ...
sprintf(' -ui %d -ui %d -ui %s &', portNum(1), portNum(2), this.terminationCode));

system( commandString );
%
%
%
%
% some algorithms
%
%
%

% how to close the cmd?

However, the function has to be looped multiple times, that means the cmd windows keep popping out like a virus without exiting. I tried system('exit') and it does not work. May I know the correct way to close the cmd window after executed the function?

Have you considered instead using the .NET interface System.Diagnostics.Process ?

Alright it turns out the command

system('taskkill /IM cmd.exe /F')

works, it required /F to force stop the cmd process

Hey Tan,

You can try passing /c along with your command string. This parameter will terminate the Windows cmd after executing the command. You can refer to it in Microsoft's documentation below:
